Effluent Characterisation Study
The European Communities (European Pollutant Release and Transfer Register) Regulations 2007 came
into operation on 22 March 2007 giving effect to Regulation (EC) No 166/2006 concerning the
establishment of a European Pollutant Release and Transfer Register (E-PRTR). Activities set out in Annex
I of Regulation (EC) No 166/2006 are required to report on their releases of PRTR substances and off-site
transfers of PRTR substances to the Environmental Protection Agency (EPA) on an annual basis.
In order to assist facility operators in the reporting of such data the EPA has developed sector-specific
excel-based Estimation tools. The Estimation tools provide facility operators with a means of estimating
releases of PRTR substances to air, water and land using best available scientific knowledge and expertise
in the absence of measured values.
This study focuses on the excel-based Estimation tool for waste water treatment plants. The Estimation
tool, in respect of releases to water, is a crude tool to estimate annual mass releases (emissions) based on
an estimate of the total volume of the annual discharge from the site. The tool is based on emission
coefficients developed using two sets of analytical data, both relating to characterisation of effluents from
Dublin City Council’s Ringsend WWTP.
The main objective of this project is to redefine the tool by capturing data from 11 UWWTPs of varying
agglomeration capacities and with different domestic and industrial inputs than the current toolset. The
revised PRTR Estimation model will provide a more representative estimation of PRTR pollutants for
reporting purposes.
Influent and effluent samples were collected from the eleven treatment plants on a quartly basis between
July 2011 and April 2012. The samples were analysed for 89 pollutants (70 of which are PRTR pollutants
relevant to water emissions with the remaining comprising of additional substances of interest to the EPA
e.g. WFD surveillance monitoring parameters of significance which have been found in Irish water courses
and some of the POPs). The relative contributions of PRTR substances from the 11 UWWTPs were
evaluated in terms of the characteristics of the treatment plant and surround catchment. Certain
parameters were identified as occurring more frequently and/or at higher concentrations in association with
particular treatment plant characteristics e.g. population equivalent served, level of treatment provided and
coastal location. Emission concentrations were generated for use in the Tool that are reflective of the
observations made regarding the concentrations of parameters associated with the treatment plant
characteristics. The emission factors were validated against historic measured data from each waste water
treatment plant included in the study.

Effluent Characterisation Study
1.1 Background
The European Communities (European Pollutant Release and Transfer Register) Regulations 2007 came
into operation on 22 March 2007 giving effect to Regulation (EC) No 166/2006 concerning the
establishment of a European Pollutant Release and Transfer Register (E-PRTR).
The E-PRTR is an inventory of pollutants of concern which are released from specified activities (through
routine discharge, accidental, fugitive and non-routine discharges) to air, water and soil, and transferred off-
site for treatment or disposal. Activities set out in Annex I of Regulation (EC) No 166/2006 are required to
report on their releases of PRTR substances and off-site transfers of PRTR substances by 31 March each
year (or 28th February in the case of waste water treatment plants). Such activities include IPPC licensed
facilities, waste licensed activities and waste water treatment plants (WWTPs) licensed by the
Environmental Protection Agency (EPA).
PRTR data is available for public inspection at facility level through the E-PRTR website
http://prtr.ec.europa.eu. This facilitates data transparency and encourages public participation in
environmental decision making. While the intention of the E-PRTR is not to regulate emissions of
pollutants, by making the data available for public inspection this encourages greater compliance amongst
industries. The reported data may also be used to track pollution trends and to focus compliance actions
towards facilities / sectors identified as having the greatest releases.
The EPA is the competent authority in Ireland for reporting PRTR data to Europe. The EPA is therefore
responsible for gathering all PRTR data from the relevant EPA-licensed facilities and for carrying out a
quality check of the reported data before it is submitted to Europe. EPA-licenced facilities are required to
submit an Annual Environmental Report (AER) before 31st March (or 28th February in the case of waste
water treatment plants) each year which must set out the environmental performance of the activity. This
must include PRTR emission data, which is to be reported in kg per annum, and waste transfer data, which
is to be reported in tonnes per annum. Facilities must report measured data where it is available (e.g. for all
parameters required to be monitored under licence conditions). The monitoring of PRTR pollutants may not
be prescribed as a licence condition and measured data may therefore not be available in all cases. In
such circumstances either a Calculated or an Estimated emission value must be reported.
Emission values may be Calculated using national or international emission models which have been
approved for use by the EPA e.g. the UN-ECE / EMEP Atmospheric Emission Inventory Guidebook. In
order to assist in deriving an Estimated emission value, the EPA has developed sector-specific excel-based
Estimation tools. The Estimation tools provide facility operators with a means of estimating releases of
PRTR substances to air, water and land using best available scientific knowledge and expertise.
1.2 Project Scope
Mott MacDonald Ireland Ltd. was appointed by the EPA on 26 May 2011 to assess the current WWTP-
specific excel-based Estimation tool1 and to broaden its applicability to a wider mix of treatment plant
agglomerations than the current version of the tool. Severn Trent Laboratories were appointed as the main
contract laboratory by Mott MacDonald. RPS Mountainheath was sub-contracted by STL to do some of the
more complex analysis.

Effluent Characterisation Study
The AER / PRTR UWWTP Emissions Calculation Toolset Version 4.0 is provided to local authorities to
assist with estimating emissions of PRTR pollutant emissions to Air and Water. The Estimation
methodology presented in the current version of the tool in respect of releases to water is a crude tool to
estimate annual mass releases (emissions) based on an estimate of the total volume of the annual
discharge from the site. The tool is based on emission coefficients developed using two sets of analytical
data, both relating to characterisation of effluents from Dublin City Council’s Ringsend WWTP. Mass loads
were calculated from the data generated in these studies and annual concentrations were estimated using
flow weighted averaging. The current version of the model is considered to be an adequate starting point
for AER/PRTR reporting purposes however the EPA decided to carry out a further effluent characterisation
exercise at additional UWWTPs to broaden the applicability of the model and in particular address a wider
combination of urban and industrial pressures than the current version of the tool.
The main objective of this project is to redefine the model by capturing data from 11 UWWTPs of varying
agglomeration capacities and with different domestic and industrial inputs than the current toolset. The
revised PRTR Estimation model will provide a more representative estimation of PRTR pollutants and
priority substances for reporting purposes.
The EPA identified eleven waste water treatment plants which were be targeted for quarterly sampling. The
location of the eleven treatment plants is shown on Figure 1.1 and they are further described in Table 1.1.

Effluent Characterisation Study
2.1 Reconnaissance of WWTP Sampling Facilities
The 11 WWTPs were visited in June 2011 to assess the sampling facilities available on site in order that a
determination may be made as to their suitability for use. Mott MacDonald Ireland and in some cases EPA
staff met with the Local Authority Staff responsible for the operation of the waste water treatment plants,
and the staff which would be assisting in the sampling. During the site visits the sampling facilities and
locations were identified and recorded. A walkover of the site was conducted to gather information
regarding the WWTP process and operation and also details of the WWTP catchment. The site visits also
allowed the identification of any issues which may impact on sampling at the selected WWTPs.
In general issues which were encountered during the site visits included; sample size, timing of sampling,
the requirement for site inductions and faulty sampling equipment. A sampling protocol and sampling
programme was developed to address these issues. Some facilities had difficulties in providing a 10L
sample over one day; this was resolved by providing a composite sample over a number of days. Where
composite samplers were not available or where sample refrigeration could not be provided, a grab sample
was provided. The sampling was co-ordinated with the Local Authority Staff to ensure sampling times did
not conflict with pre-existing sampling requirements and that the Laboratory Staff were scheduled to collect
the sample on that day.
Following on from the site visits, a Site Pack for Samplers was prepared; this document included the
protocol for sampling and site information. Field Data Sheets were also issued to the Local Authority Staff
which included a section to be completed by the plant operator at the time of sampling. Information
gathered from field sheets, was utilised in the assessment of the monitoring results.
2.2 Sampling Programme
Each WWTP caretaker/operator was contacted one week before the scheduled sampling date to ascertain
whether there were any contraindications to proceeding with the sampling e.g. plant failure etc.
The first round of sampling was conducted on 19th to 21
st July (inclusive). All samples were collected on
schedule and there were no issues with the delivery to the labs.
The second round of sampling was scheduled to take place between 24th October and 26
th October 2011
inclusive. However a decision had to be taken to postpone the sampling at the Ringsend WWTP due to
extreme weather conditions during the previous week. Heavy rainfall causing flooding within the catchment
resulted in very sludgy waste water entering the treatment plant which the plant operator described as not
representative of the typical waste water from the agglomeration. Sampling was rescheduled to take place
on the following Wednesday 2nd
November. Sampling at the Watergrasshill WWTP took place on 31st
October to accommodate the caretaker’s annual leave. Sampling at Ballinasloe took place on 2nd
November to accommodate the caretaker. Sampling at all other plants was as scheduled.
During the transfer of the samples for the second round of sampling the logistics company damaged and
misdirected some of the boxes therefore not all of the required sample bottles were delivered to the
laboratory. At the time of sampling, additional spare sample containers were filled to cover such an
eventuality. However given the large sample volume required (10L) for the PRTR analysis and the number

of boxes damaged, it was estimated that the lab would still be short sample. Also, because of the way the
samples are shipped, it was not clear at the early stage which WWTPs were affected. As a precautionary
measure each of the WWTPs was revisited to collect more sample during the period 14th – 16th
November. The analysis conducted using the samples from the revisit are outlined in Table 2.1.

Effluent Characterisation Study
2.3 Analysis
The quarterly influent and effluent samples taken from the 11 waste water treatment plants were to be
analysed for 89 pollutants (70 of which are PRTR pollutants relevant to water emissions with the remaining
comprising of additional substances of interest to the EPA e.g. WFD surveillance monitoring parameters of
significance which have been found in Irish water courses and some of the POPs). Table 2.3 identifies the
substances included in the study.
Following the first round of sampling it became evident that the limits of detection (LODs) prescribed in the
project brief could not be achieved for certain parameters. Due to the nature of the samples (influent and
effluent waste waters), there was a high level of interference. Difficulties were encountered in reading the
peaks on the chromatograms due to interference from the sample matrix. The presence or absence of the
parameter being analysed for could not be stated with certainty in such circumstances. In order to
overcome this problem the sample was diluted to make it ‘cleaner’ until such time as an accurate reading
could be made. The effect of diluting the sample was that the fixed proportion of water added had to be
accounted for by raising the LOD. The result being that the LODs prescribed in the brief for some
parameters could not be achieved.
Following consultation with the EPA it was agreed to proceed on the basis that some samples would
require dilution and that the best attainable LODs would be reported. Parameters for which this approach
was agreed are noted as ‘Best Attainable’ in Table 2.3.
It is important to bear in mind that the levels of dilution required to facilitate an accurate reading varied
between parameters and also from sample to sample and ranged anywhere from 10 dilutions to >500
dilutions. The LODs reported are in some cases therefore different between waste water treatment plants.
The raised LODs reported are also different between each round of sampling conducted to date. This has
an inhibitory effect when cross-comparing waste water treatment plants against each other and against
each round of sampling.
For other parameters, namely Chloro-alkanes C10 - C13, Halogenated Organic Compounds (as AOX) and
Dicofol, difficulties were encountered in method development and no result could be provided. While for
others the method development facilitated the reporting of a result at a much higher LOD than required,
namely Chlordecone, and Hexabromocyclododecane (HBCD). The decision was taken to excluded Chloro-
alkanes C10 - C13, Halogenated Organic Compounds (as AOX) and Dicofol from further analysis as
indicated by ‘Not Achievable’ in Table 2.3 and to continue the analysis of Chlordecone, and
Hexabromocyclododecane (HBCD) at the agreed higher reporting limit, as indicated in bold in

Note 1: LODs identified in bold are those where reporting of higher LODs has been accepted.
Note 2: in round 4 analysis Arsenic, Cadmium, Chromium, Lead and Tin were analysed to a reporting limit of 0.1 µg/l
Following the examination of the results from the second round of sampling the value of continuing to
sample both the influent and effluent for certain parameters that are reported as <LOD and that have
elevated LODs associated was questioned. The following decisions were therefore taken:
• Analysis of Organotins, Metals, General parameters and Phenols should be continued on all
influent samples;
• The analysis of influent for all other parameters is to be discontinued;
• Effluents shall be analysed as before (Note it was decided that PFOS and
Hexabromocycododecane analysis would be continued in the effluent).
Table 2.4 provides a summary of whether analysis of influent and effluent samples was conducted per
group of substances included in the third round of sampling.

Following the examination of the results from the third round of sampling it was determined that Round
Four analysis should continue as per Round Three with the following amendments:
1. Arsenic, Cadmium, Chromium, Lead and Tin are to be tested by Low Level ICP_MS, all other
metals are to be analysed as per round three;
2. Additional Polybrominated diphenylethers congeners are to be reported. The full suite shall
therefore include Tetrabromodiphenyl ether, Hexabromodiphenyl ether, Pentabromodiphenyl ether,
Heptabromodiphenyl ether, Decabromodiphenyl ether, Octabromodiphenyl ether, and
Nonabromodiphenyl ether.

Effluent Characterisation Study
3.1 Introduction
The results of analysis for sampling Rounds one to four are presented in Appendix A. A summary of the
results is presented under the following PRTR parameter groups:
• General Parameters
• Metals
• Pesticides
• Triazine Herbicides
• Substituted Ureas
• Organotin compounds
• Acid Herbicides
• PAHs
• PCBs – Pesticides and others
• Phenols
• sVOCs
• Organic Fluorochemicals
• Polybrominated diphenylether
The results are presented with regard to the detection of each parameter above the LOD in the influent and
effluent samples. Those parameters detected above the LOD are evaluated with regard to the range of
concentrations present in the influent and effluents of Irish WWTPs. These parameters are considered with
regard to their fate in the wastewater treatment plant and seasonal variations. A further detailed
assessment of the catchment characteristics which may influence the concentrations of these parameters
is presented in Section 4.0, this assessment forms the basis of the Estimation tool development.

Effluent Characterisation Study
The General Parameters (with the exception of cyanide) are ubiquitous in Irish wastewaters and in almost
all cases were measured above the LOD. Cyanide was detected in the Ballinalsoe WWTP Influent just
above the LOD in Round 2 and in the Waterford and Newcastle West influent samples in Round 4. Cyanide
was detected in the effluent of Carrigrennan WWTP in Round 1 and 3 and just above the LOD in the
Balliasloe effluent sample in Round 4.
Total Nitrogen concentrations in the influent of samples taken in Round 1 were generally higher than those
for Rounds 2, 3 and 4. Influent concentrations for Total Phosphorus were low at a number of plants. Total
Nitrogen and Total Phosphorus concentrations in the effluents were lower in the WWTPs that had nutrient
reduction as part of the treatment process.
There was significant variation in influent TOC concentrations between sampling rounds, most plants had
lowest TOC concentrations in Round 2, and this may be as a result of rainfall prior to sampling. However
effluent TOC concentrations were less variable over the rounds, which indicate good consistent TOC
removal rates at the WWTPs.
Chlorides and conductivity were detected in higher concentrations in influent and effluent samples from the
4 coastal WWTPs (Carrigrennan, Dundalk, Ringsend and Waterford WWTPs) which were expected due to
their location and saline intrusion.
Fluorides mostly exist in wastewater samples due to the fluoridation of water supplies. Fluoride was
detected above the LOD (<0.2mg/l) in most samples over Rounds 1 to 4. Fluoridation of public water
supplies is a regulatory requirement, under the Fluoridation of Water Supplies Regulations, 2007 and the
amount of fluoride which may be added to the public water supplies shall be such that the water, after the
addition of fluoride, the minimum concentration of fluoride is 0.6 mg/l with a maximum concentration of 0.8
mg/l. Only 1 sample (Ringsend Effluent Round 1) was above 0.8 mg/l at 1.5 mg/l.
Total Hardness is normally a function of the geology of the area and hence reflected in the water
composition. Carrigrennan reported the highest Total Hardness over the 4 rounds of testing, although lower
concentrations were detected in Round 4. High Total Hardness may be linked to specific industries with
water softeners e.g. Commercial Laundries, Pharmaceuticals etc. It is likely that the concentrations
detected are related to the saline intrusion in the catchment (total hardness of seawater is in the region of
6630mg/l CaCO3).
The pH ranges at the WWTPs are typical of that necessary to support the aerobic biological treatment
processes employed at the 11 WWTPs. Only one sample (Portarlington Influent Round 3) was outside this
range at 5.6. This may be related to the buffering capacity of the water.
Table 3.1 and Table 3.2 set out the range of concentrations which were detected at the 11 WWTPs during
each Round of sampling.

Sampling Round 1 (July 2011) Sampling Round 2 (Oct 2011)
Sampling Round 3 (Jan 2012) Sampling Round 4 (April 2012)
Vanadium was also detected in a high number of samples, detected in 30 of 44 influent samples and 32 of
44 effluent samples. Vanadium was not detected above the LOD in Round 4. Nickel was detected above
the LOD in 37 of 44 influent samples and 30 of 44 effluent samples. Copper was detected in 34 of 44
influent samples and 24 of 44 effluent samples. Arsenic was detected in 34 of 44 influent samples, and in
23 of 44 effluent samples.
Chromium was detected above the LOD in 27 influent samples in Rounds 1 and 4, it was not detected in
Round 2, however the LOD was raised from <0.7 µg/l to <2 µg/l in Round 2.
Lead was detected in 32 of 44 influent samples and 26 of 44 effluent samples with much less detection
above the LOD in Round 2 and Round 3.
Selenium, Antimony and Cobalt, were detected in fewer influent and effluent samples, no trend was noted
with regard to seasonal variation.
Mercury was detected above the LOD in 10 influent samples, again no seasonal trend was identified.
Mercury was not measured above in the LOD in any effluent sample.
Boron is likely to be ubiquitous in wastewater due to its use in soaps and detergents. The European
Communities (Drinking Water) Regulations, 2000 set a concentration of 1mg/l for Boron, all samples are
below this concentration. Boron is present in seawater at concentrations of 5mg/l which is reflected in
higher influent and effluent samples from the 4 coastal WWTPs (Carrigrennan, Dundalk, Ringsend and
Waterford WWTPs). Boron had higher numbers of detections above the LOD in Rounds 2 and 3. The LOD
was raised to <230mg/l in Round 4.

Sampling Round 1 (July 2011) Sampling Round 2 (Oct 2011)
Sampling Round 3 (Jan 2012) Sampling Round 4 (April 2012)
It is of note that metal detection above the LOD in Round 2 was significantly lower than for the other rounds
of sampling. It is considered that the low concentrations may be attributable to the storm conditions
experienced immediately before and during the sampling.
Metal analysis for Round 3 provided a number of questionable results; most notably Molybdenum was
detected at very high concentrations in all effluent and influent samples. The decision was taken to exclude
all Round 3 metal results from the study for the purpose of developing the Tool.
Table 3.3 and Table 3.4 set out the range of metal concentrations at the 11 WWTPs during each Round of
sampling.

Concentrations of pesticides may be reported below the LOD because:
� Some parameters are banned and their presence would not be expected.
� Intermittent use only will be detectable if a rainfall event occurs after application.
Pesticides which were measured above the LOD in the Influent Samples (Round 1 and 2 only) include:
� Dichlobenil (5 samples in Round 1 and 4 samples in Round 2)
� Lindane (1 sample in Round 1 and 2 samples in Round 2)
� Mirex (2 samples in Round 1)
� Dieldrin (1 sample in Round 1)
� Chlorpyrifos (1 sample in Round 1)
Of which only the following were detected above the LOD in the effluent samples:
� Dichlobenil (5 samples in Round 1, 6 samples in Round 2, 2 samples in Round 3, and 3 samples in
Round 4)
� Lindane (1 sample in Round 1, 2 samples in Round 2 and 1 sample in Round 3)
� Chlorpyrifos (1 sample in Round 3)
The majority of the pesticides were detected in the summer, when use is more prevalent.

Sampling Round 1 (July 2011) Sampling Round 2 (Oct 2011)
Sampling Round 3 (Jan 2012) Sampling Round 4 (April 2012)
Dichlobenil was measured in the influent to 5 WWTPs, at concentrations of 0.002 µg/l to 0.006 µg/l. It was
however detected in the effluent from 8 WWTPs at concentrations of 0.002 µg/l to 0.045 µg/l. Only 3
WWTPs, namely Newcastle West, Carrigrennan and Watergrasshill did not report Dichlobenil above the
LOD in either influent or effluent samples. There is very little information currently available on the fate of
Dichlobenil in WWTPs, the results would suggest that removal rates in WWTP are low. There were fewer
detections of Dichlobenil in the effluent samples in Round 3, a greater number of samples were measured
above the LOD during summer and autumn (Rounds 1 and 2), with highest concentrations overall detected
in the summer.
Lindane was measured above the LOD in the samples at 3 WWTPs, Dundalk, Ringsend and
Watergrasshill, in most cases if Lindane was detected in the influent it was also detected in the effluent at
similar concentrations. There was a greater number of detections in Round 2 effluent, although the
numbers measured above the LOD are still very low. Use of Lindane has been banned in the European
Union
Mirex was detected in only one sample. Use of Mirex has been banned in the European Union although it
is persistent, with high removal rates reported in the activated sludge process.
It should be noted that due to difficulties experienced in recovering Chlorodecane, the reporting limit for this
compound was raised to <8000 ng/l in Round 3.
Table 3.5 and Table 3.6 set out the range of concentrations which were detected at the 11 WWTPs during
each Round of sampling.

Linuron, Triphenyltin, Organotin and Tributyltin were not detected above the LOD in any sample, which
may be attributed to the fact that their use is restricted in Ireland.
Parameters which were measured above the LOD in the influent (Round 1 and 2 only) include:
� Glyphosate (11 samples Round 1 and 10 samples Round 2)

Effluent Characterisation Study
Glyphosate was measured above the LOD (i.e. 0.1 ug/l) in all samples in Round 1 and Round 4, with
slightly fewer samples reporting above the LOD in Round 2, although at much lower concentrations. This
may indicate significantly higher widespread usage in summer months. As the LOD (i.e. 5 ug/l) for the
effluent samples was raised in Round 3 due to chromatographic interference, it is not possible to draw any
conclusions from Round 3 results.

MCPA and 2,4-D were also detected in a number of WWTPs. MCPA was not detected in Round 2 effluent
samples and at only 1 WWTP in Round 3. MCPA and 2,4-D are typically applied in Spring/Summer
between May and June. This correlates with the higher concentrations recorded in Rounds 1 and 4.

3.6 PAHs
Polycyclic aromatic hydrocarbons (PAHs) arise from incomplete combustion or pyrolysis of organic
substances such as wood, carbon or mineral, they may also be utilised in the manufacture of
pharmaceuticals, pesticides and dyes, and as such are likely to be present in wastewaters. Note that
influent monitoring was undertaken in Round 1 and 2 only.

All PAHs tested were measured above the LOD in at least one influent sample in Round 1, with Total PAH,
Anthracene, Naphthalene and Fluoranthene the only PAHs detected above the LOD in influent samples in
Round 2. The effluent samples had fewer numbers of parameters and samples detected above the LOD.
Parameters such as Total PAHs, Indeno[1,2,3-c-d]pyrene, Benzo[g,h,i]perylene, Anthracene, Naphthalene
and Fluoranthene have reported high removal rates (70-90%) in activated sludge plants, which may
account for fewer measured samples above the LOD in the effluent. The maximum effluent concentration
of 0.113 µg/l was recorded in the Athlone WWTP in Round 4.

Naphthalene was recorded above the LOD in the influent of 9 of the 11 treatment plants in Round 1 and at
4 of the 11 treatment plants in Round 2. Higher concentrations were recorded in Round 2, which may
indicate a link with runoff in the catchments. Highest effluent concentrations of 0.063 µg/l were recorded at

Sampling Round 1 (July 2011) Sampling Round 2 (Oct 2011)
Sampling Round 3 (Jan 2012) Sampling Round 4 (April 2012)
PCBs were not measured above the LOD in any samples; this may be as they have been withdrawn from
use.
Tetrachloromethane was not detected. Tetrachloromethane was commonly used as a dry-cleaning agent, a
degreasing agent, a fire extinguishant and a pesticide, these uses are now banned. Tetrachloromethane is
from industrial spillages and from landfill sites where waste containing TCM has been buried. Releases of
TCM rapidly evaporate into the air.
Tetrachloroethylene and Dichloromethane were measured above the LOD in a small number of samples
both in the influent and effluent (Rounds 2 and 3).
Dichloromethane was measured above the LOD at only two WWTPs, namely Carrigrennan and Waterford
WWTP in Rounds 2 and 3, with a maximum concentration of 14.7µg/l (Round 3 influent Carrigrennan).
The main uses of dichloromethane are in paint removers, aerosol solvents, in the manufacture of certain
pharmaceuticals, and as a degreasing agent in the electronics industries. The corresponding effluent
concentration in Carrigrennan in Round 3 was 2 µg/l. This may be associated with industrial discharges
these catchments.
Tetrachloroethylene was detected the influent of two WWTPs, Newcastle West and Ballinalsoe, the
maximum concentration detected was 1.6 µg/l. It was also measured above the LOD in the effluent from
the Ringsend WWTP in Round 3 at 2.6 µg/l. The main use of PER is as a dry-cleaning agent for textiles
and fabrics. It is also used for metal degreasing and is used in some consumer products.
Parameters which were not measured above the LOD include:
� PCBs
� Tetrachloromethane (or Carbon Tetrachloride)
� Trichloroethylene
289584/IWE/R/04/A 05 September 2012 20120905 - 289584 - Part A Final Report.doc
35
Effluent Characterisation Study
� Vinyl Chloride
� 1,2-dichloroethane
The absence of PCBs and Tetrachloromethane (Carbon Tetrachloride) in the wastewaters may be as a
result of their withdrawal from use or restrictions in use. Tetrachloromethane may be present in landfill
leachate, although it was not measured at any of the WWTPs which receive landfill leachate.
Trichloroethylene, Vinyl Chloride and 1,2-dichloroethane were not measured above the LOD in any

be present in Irish wastewaters at levels currently measurable.

Sampling Round 1 (July 2011) Sampling Round 2 (Oct 2011)
Sampling Round 3 (Jan 2012) Sampling Round 4 (April 2012)
The parameters which were detected above the LOD in the influent samples (Rounds 1 and 2) included:
� Benzene
� Toluene
� Xylene
� Ethyl benzene
� Di(2-ethylhexyl)phthalate
Many of these parameters were not measured above the LOD with the same frequency in effluent samples,
this may be due to high volatility and high removal rates in WWTPs of these parameters. There was a
greater frequency of detection in Round 3. Benzene, Ethyl benzene and toluene were present in the
influent, highest concentrations recorded at Dundalk and Blarney.
2,6-Dichlorobenzamide was not measured in the influent samples above the LOD, although was detected
in the effluent of 3 WWTPs in Round 3 and 10 WWTPs in Round 4 with a maximum concentration of 0.25
µg/l at Dundalk. Dichlobenil of which 2,6-Dichlorobenzamide is a metabolite was detected in the majority of
WWTPs (refer to Section 3.4). However the LODs achievable for Dichlobenil (<0.002 µg/l) are significantly
lower than those achievable for 2,6-Dichlorobenzamide (<0.06 µg/l). Whilst there is a difference in the
achievable LODs, it may be deduced that the metabolite of Dichlobenil is likely to be present in effluents
from Irish WWTPs.
Di(2-ethylhexyl)phthalate (DEHP) was measured in almost all (21 of 22) influent samples. This was
anticipated due to its use as an additive to plastics. The LOD for the effluent was raised in Round 1 (<1.0
µg/l), with only one sample above the LOD, i.e. 1.2 µg/l (at Mitchelstown), the required LOD was achieved

in Rounds 2, 3, and 4 which reported all samples above the LOD in the range of 0.07 to 3 µg/l. In most
cases effluent concentrations Round 3 and 4 were higher than those in Round 2.

Toluene was measured in the influent ranging from 0.17 to 270 µg/l with highest concentrations recorded in
Carrigrennan. Toluene was consistently detected in the effluent samples of Mitchelstown. Mitchelstown is
the only WWTP which employs trickling filters, and which may suggest lower removal rates with this type of
treatment.

Effluent Characterisation Study
4.1 Introduction
The EPA’s AER / PRTR UWWTP Emissions Calculation Toolset Version 4.0 in respect of releases to water
is a crude tool to estimate annual mass releases (emissions) of PRTR substances from WWTPs based on
an estimate of the total volume of the annual effluent discharge from the site. The tool provides a
mechanism by which annual loads to water can be estimated where no monitoring data exists. The
estimated loads to water are based on emission coefficients developed using two sets of analytical data:
• Priority Study Dataset (2006 – 2006) was derived from the National Dangerous Substances Screening
Programme conducted by the SERBD Project with expert guidance from the EPA and others.
Complex laboratory analysis was undertaken on 11 separate sampling events which were conducted
at approximately monthly intervals. The samples were analyzed for a list of 217 individual substances
(including 41 Priority Action Substances, 20 General Components and 156 Relevant Pollutants).
Ringsend WWTP was one of the sites that was monitored. The results from the Ringsend treatment
plant were used to develop the EPA’s AER / PRTR UWWTP Emissions Calculation Toolset Version
4.0.
• Ringsend Characterization Study (2008) included the analysis of a single set of samples (1 influent
and 1 effluent sample) taken from Ringsend WWTP in April 2008 on behalf of Dublin City Council. The
analysis was undertaken by a UKAS accredited laboratory. The following parameter suites were
analyzed as part of this study: metals and general components, organochlorine pesticides,
organophosphorus pesticides, substituted ureas, triazine herbicides, organotins, acid herbicides,
PAHs, PCBs, Phenols and semi VOCs.
This study assessed the current version of the EPA’s AER / PRTR UWWTP Emissions Calculation Toolset
Version 4.0 with respect to its application to emissions to water with the objective of providing a better
estimate of mass emissions based on monitoring from a wider range of waste water treatment plants. To
that end quarterly samples were taken between 19th July 2011 and 19
th April 2012 at the 11 waste water
treatment plants included in this study. The intention of the effluent sampling is to provide a wider base of
data upon which the Tool may be updated and to broaden the current understanding of PRTR substance
presence in waste water treatment plant discharges in Ireland. The results of analysis are provided in
Section 3 of this Report.
The occurrence and concentration of PRTR substances in the samples taken from the 11 treatment plants

For the purpose of assessing the relationship between PRTR substances and treatment plant
characteristics, where the results of analysis were reported as not being present in a concentration above
the limit of detection (i.e. reported as <LOD) the substance was taken not to be present i.e. a value of zero
was applied. The investigation focused on results of effluent analysis as this is ultimately what is to be
utilised in the Estimation Toolset however regard was also had to the results of influent analysis where
appropriate.
The presence of PRTR substances in an effluent discharge from a waste water treatment plant is
dependant upon a number of factors as follows:
1. Activities in the Catchment
� Population Equivalent (PE) – PE is a representation of the total load to the waste water treatment
based on BOD loading. The pollution load to the treatment plant is influenced by the population
living in the catchment and the level of commercial and industrial activity in the catchment. A
greater prevalence and diversity of PRTR pollutants would be expected in urban catchments as
they are more densely populated and generally contain a larger number and greater variety of
industrial and commercial activities.
� Domestic / Non-Domestic Contribution – Plants with a greater non domestic contribution are
expected to have a broader range of PRTR substances in their effluent than those with lowner
numbers of commercial and industrial activities in their catchment.
� Water Supply – The constituents of a water supply are source specific where PRTR substances
are present these may be measured in the waste water treatment plant serving the catchment.
2. Type of collection system feeding the treatment works (i.e. combined or separate foul). Storm water
runoff can contain higher levels of certain PRTR substances but can also have the effect of diluting the
concentration of other substances.
3. Level and type of treatment at the plant will influence the removal efficiencies within the plant and
therefore the final effluent constituents.
4. Whether the treatment plant is located coastally or inland can influence the concentration of certain
parameters. Coastally located plants subject to saline intrusion will have higher concentrations of
parameters that are found in sea water.
The relative contributions of PRTR substances from the 11 WWTPs included in this study were evaluated
in terms of the catchment and treatment plant characteristics. The following data sources were referenced
for catchment and treatment plant characteristic information:
• UWWD licence applications and licences (currently 9 of the 11 WWTPs have a WWDL)
• Annual Environmental Reports

4.2 Catchment and Treatment Plant Characteristics & Trends in the Occurrence and Concentration of PRTR Substances
4.2.1 Activities in the Catchment
Direct inputs of PRTR substances to a waste water treatment facility occur from three principal sources
from within the catchment: domestic discharges, commercial discharges, and industrial discharges.
Major domestic sources of PRTR pollutants include faeces (which contain metals and pharmaceutical
residues), sanitation waste water (which include chemicals in body care and makeup products, chemicals
in cleaning products and detergents and also the chemicals which are inherent to the water supply). Other
domestic sources include the release of liquid wastes into the drain which may include paints, gardening
products etc. The plumbing system will also influence certain metal concentrations in the waste water and
is influenced by water hardness.
Commercial sources include discharges from small businesses which may include dry cleaners, dentists,
petrol stations, hairdressers, hospitals, bus/train stations, golf courses, and education facilities e.g.
universities. The majority of these commercial activities are sub-threshold to the First Schedule of the
Protection of the Environment Act, 2003 and therefore do not require an IPPC licence. These facilities
should however be licenced under Section 16 of the Local Government (Water Pollution) Act, 1977 where
they are discharging a trade effluent to sewer.
Many industrial activities use PRTR substances as part of their production activities. The PRTR
contribution to a waste water treatment plant is catchment specific as it is dependant on the type of
industrial activities (amongst others) within the catchment. Industrial activities are licensable by IPPC and
Waste licence. Some PRTR substances are common to may different types of industry and it is difficult
therefore to attribute the presence of a substance to a particular industry.
Population Equivalent (PE)
Of the eleven waste water treatment plants included in this study, three had a PE of between 2,000 and
10,000 (Newcastle West, Mitchelstown and Watergrasshill) four plants had a PE of 10,000 to 50,000
(Ballinasloe, Athlone, Portarlington and Blarney) and four had a PE of greater than 50,000 (Carrigrennan,
Ringsend, Waterford and Dundalk).
It is expected that a greater range and load of PRTR substances would be found in the effluent of waste
water treatment plants with a high PE because they are typically associated with urban areas with higher
population and likely to support higher and more diverse industrial / commercial activity.
It cannot however be concluded with certainty that where a substance is not seen in the effluent at a
treatment plant that it is not being produced in the catchment, as the type and level of treatment at a
289584/IWE/R/04/A 05 September 2012 20120905 - 289584 - Part A Final Report.doc

Effluent Characterisation Study
treatment plant will influence PRTR substances in the effluent. Regard must therefore also be had to the
influent monitoring carried out under this study to reaffirm or otherwise any correlation identified between
population equivalent and concentration in the effluent.
General Parameters
No direct correlation between PE and the occurrance and concentration of nutrients in the effluent could be
determined with the exception of Total Phosphorus which was slightly higher in the effluent of plants with
>50,000 PE. Influent concentrations were not however higher in these plants. The plants with >50,000PE
do not provide phosphorus removal and it is therefore more likely a feature of the level of treatment rather
than PE.

Total nitrogen (as N) Total phosphorus (as P)
Plants with a PE of >50,000 had higher concentrations of chlorides and had higher conductivity and total
hardness values. This is coincidental to the fact that these plants are all located coastally and are likely to
be influenced by saline intrusion.
Cyanides have only been detected in the effluent of the Carrigrennan and Blarney waste water treatment
plants and in the influent of the Ballinasloe, Newcastle West and Waterford treatment plants.
Fluorides in waste water are a function of water supply and catchment activities. Generally, slightly higher
concentrations were recorded in the influent and effluent of treatment plants >50,000 PE. The average
effluent concentration in plants >50,000 PE was 0.55mg/l as opposed to 0.19 mg/l for plants less than
50,000 PE. The fluoride concentrations in the influent to the treatment plants will be influenced by the
extent of leakage of mains water to the sewer. Note that interference by carbonate ions in the analysis, due

to saline intrusuion in the catchment, was considered and expected not to be the cause of higher fluoride
concentrations as the samples are buffered using a reagent to compensate for interference.

Metals
Metal analysis for Round 3 provided a number of questionable results; most notably Molybdenum
was detected at very high concentrations in all effluent and influent samples. The decision was
taken to exclude all Round 3 metal results from the study for the purpose of developing the Tool.
Mercury was not found above the LOD in the effluent of any waste water treatment plant.
Cadmium was found in the effluent of treatment plants across all PE bands but was recorded at slightly
higher concentrations in plants in the 2,000 to 10,000 PE band.

Selenium was only found in the effluent of treatment plants of >50,000 PE.
Copper, nickel, zinc, vanadium were recorded across all PE bands. No obvious correlation to the PE bands
was discernible.
Chromium, cobalt, tin and antimony were recorded above the LOD at only a small number of samples but
were ubiquitous to all PE bands. No obvious correlation to the PE bands was discernible.
Barium was ubiquitous to all effluent discharges. Lower concentrations were noted in plants within the
2,000 to 10,000 PE band, with an average concentration of 12.47µg/l as opposed to an average of
22.98µg/l for plants >50,000 PE.

Arsenic was generally more prevalent in the effluent of waste water treatment plants >50,000PE.
Concentrations were also generally higher in both the influent and effluent. An average effluent
concentration of 0.002mg/l was recorded at plants >50,000PE whereas an average concentration of
0.0003mg/l and 0.0005mg/l was recorded at 10,000 to 50,000 PE and 2,000 to 10,000 PE plants
respectively. The higher concentrations in the influent of plants >50,000PE may be a function of industrial
activity. It is of note however that the larger plants are located coastally. Arsenic in sea water is typically in
the range of 0.001mg/l to 0.005mg/l. The average influent concentration of plants >50,000PE was
0.002mg/l. It is likely that the higher concentrations are due to saline intrusion in the catchment.

Pesticides
The use of many pesticides in Europe has been banned progressively since the 1980’s. The effects of the
ban are evident in the results of sample analysis at the eleven waste water treatment plants. The following
parameters, for which a ban exists, were not detected above the LOD in any influent or effluent sample:
Alachlor, Aldrin, Endrin, Heptachlor, Chlordane, Isodrin, DDT, Trifluralin, Hexachlorobenzene (HCB),
Chlorfenvinphos, Chlordecone, Hexachlorobutadiene (HCBD)2.
A ban on the use of Dieldrin, Mirex and Endosulphan also exists, however these parameters were recorded
at low concentrations in a very small number of influent samples. They are persistent in nature and may
therefore exist in the environment long beyond the cessation of their use. These parameters were recorded
in three influent samples above the LOD in the first round of sampling only, which took place in July 2011.
Volatization is one of the main mechanisms by which such substances are desorbed from sediment/soil.
Volatization is affected by climate with higher rates occurring at higher temperatures. It is logical then that
we might see these persistent substances in influent samples on a seasonal basis (other factors will also
be influential e.g. humic content, moisture, biodegradation). Dieldrin, Mirex and Endosulphan were not
recorded above the LOD in any effluent sample. Activated sludge has high removal efficiencies for such
substances.
Lindane (1,2,3,4,5,6 -hexachlorocyclohexane), Chlorpyrifos and Dichlobenil were detected above the LOD
at a number of waste water treatment plants across all PE bands. The use of lindane is banned in Europe
since 2009. Lindane is persistent and, considering how recently its use has been banned, it is not
surprising that it was recorded above the LOD in a number of treatment plants, namely Dundalk, Ringsend
and Watergrasshill. Chlorpyrifos is used as an insecticide in Ireland. Chlorpyrifos was only detected above
the LOD in one influent sample (Watergrasshill – Round 1) and one effluent sample (Ringsend – Round 3)
at concentrations close to the LOD. Dichlobenil was detected across all PE bands. Highest concentrations
were recorded at Ballinasloe.
The concentrations at which the above substances were detected can be influenced by the timings
between their application and the taking of the sample as well as the precipitation levels immediately
at/before the time of taking the sample. Pesticide application typically takes place during the summer
months (during crop growth) and immediately before harvest i.e. from May through to September/October.
It is therefore expected that highest concentrations would be observed in the samples from Round 1 and 2
and lowest concentrations from Rounds 3 and 4 (which were taken outside the growing/harvest season).
_________________________ 2 Note the higher reporting limit on Chlordecone, Hexachlorobutadiene (HCBD).

Triazine Herbicides, Substituted Ureas, Organotin Compounds and Acid Herbicides
Restrictions for the protection of the environment are in place across Europe regarding the application of
certain herbicides. The effects of the restrictions on use can be seen in the analytical results.
The use of Atrazine and Simazine is restricted in Ireland. They were detected in only a small number of
samples. Their usage is seasonal and associated with agricultural / horticultural activities. They were also
used historically for the maintenance of road verges.

Substituted Ureas usage is restricted in Ireland. Linuron was not detected in any influent or effluent sample
with Isoproturon only detected in one effluent sample in Round 3 (Dundalk). Diuron was only detected in
the Newcastle West treatment plant (in Round 2 and Round 4). No correlation with PE band could be
established.
Organotins were not recorded above the LOD in any of the influent or effluent samples. This is reflective of
the restriction on their use in Ireland.
Acid herbicides are used widely throughout Ireland in agricultural and grassland maintenance in both rural
and urban environments. Their presence is across all PE bands. Herbicide concentration recorded at
Newcastle West in Round 4 was high. This may be attributed to runoff from the catchment due to the heavy
rainfall experienced in the area on the day of sampling.

Concentrations of Glyphosate were highest in Round 1. This is as expected due to seasonal usage. Note
that the LOD (i.e. 5 ug/l) for the effluent samples was raised in Round 3 due to chromatographic
interference; it is not therefore possible to draw any conclusions from Round 3 results as all were below the
LOD. Slightly higher concentration were detected in the influent of WWTPS >50,000PE which may be
reflective of its use for the maintenance of roadside vegetation.

Results of PAH analysis show that there is a higher frequency of occurrence and a higher concentration of
PAHs in the influent samples taken from the larger waste water treatment plants i.e. those with a >50,000
PE. PAHs are associated with industrial activity and road runoff which tend to be more intense in urban
settings. There are high removal efficiencies for PAHs using activated sludge as can be seen by the low
effluent concentrations.

Effluent Characterisation Study
PCBs- Pesticides and Others
Tetrachloroethylene (PER) and Dichloromethane (DCM) were the only parameters under this category that
were detected in the influent and effluent samples. Tetrachloroethylene (PER) is as a dry-cleaning agent
and was recorded above the LOD across all PE bands. Dichloromethane (DCM) has a variety of industrial
uses including in the pharmaceutical industry and was recorded above the LOD in the influent and effluent
of plants >50,000 PE only. DCM was however recorded in such a small number of samples (only one
effluent sample – Carrigrennan round 3) that a strong correlation with PE could not be established.
SVOCs
The following parameters were not detected above the LOD in any effluent sample: Trichlorobenzenes
(TCBs) (all isomers), Pentachlorophenol (PCP), Pentachlorobenzene, Hexabromocyclododecane (HBCD),
Toxaphene, Hexabromobiphenyl. SVOCs were detected across all PE bands.

Phenols, Organic Fluorochemicals, and Polybrominated diphenylethers
Phenols were recorded across all PE bands in influent samples. Concentrations in the influent of the
Carrigrennan treatment plant were several orders of magnitude higher than that recorded in the other
plants in Rounds 1 and 3 and are understood to be associated with local industry.
PFOS3 was observed above the LOD in only one effluent sample (Dundalk – Round 3).
Polybrominated diphenylethers were not observed above the LOD in the influent or effluent samples of any
of the eleven treatment plants.

Domestic / Non-Domestic Contribution
Of the waste water treatment plants included in this survey, five of the eleven plants serve catchments with
>50% industrial/commercial contribution while four have <20% industrial/commercial contribution. It is
expected that a greater number of PRTR substances and a greater concentration of PRTR substances
would be found in the effluent of waste water treatment plants that service a high non-domestic load.

<20% Non Domestic Contribution21 - 49% Non Domestic Contribution>50% Non Domestic Contribution
It should be noted that a treatment plant may receive a high percentage of non-domestic wastewater which
may be dominated by ‘low risk’ commercial activities which do not contain significant amounts of PRTR
substances as opposed to a catchment whose non-domestic contribution comprises of heavy industry. It is
therefore important that the level of industrial activity in a catchment is also considered as a separate entity
when considering the impact on non-domestic contribution on PRTR substances at a waste water
treatment plant.
Sources of data on industries that discharge to sewer within a catchment include the EPA (IPPC and waste
licences) and the local authority (licences under Section 16 of the Local Government Water Pollution Act,
1977). The EPA maintains good IPPC and waste licence records and these are readily available through
their website www.epa.ie. Records of licences issued under the Water Pollution Act are not as up to date
as IPPC records. It was not feasible therefore to take Section 16 discharges into consideration as part of
this study.

General Parameters
No direct correlation between non-domestic contribution and the presence / absence and concentration of
general parameters in the effluent could be determined, with the exception of fluoride concentrations.
Fluorides were generally recorded at higher concentrations in treatment plants with higher levels of non-
domestic contribution in their catchments. Fluoride in waste water is a function of the type of water supply
and the extent of leakage of mains water to the sewer aswell as the type and level of industrial activity in
the catchment.

Effluent Characterisation Study
Metals
Metal analysis for Round 3 provided a number of questionable results; most notably Molybdenum
was detected at very high concentrations in all effluent and influent samples. The decision was
taken to exclude all Round 3 metal results from the study for the purpose of developing the Tool.
Cobalt results did show slightly higher concentrations in the influent samples of treatment plants with <20%
non-domestic contribution however due to the low number of results recorded above the LOD 9only 2
samples in total), a strong correlation cannot be stated with confidence.
Selenium was largely associated with treatment plants serving a higher number of IPPC licenced facilities.
Arsenic was recorded at lower concentrations in the effluent of treatment plants with <20% non-domestic
contribution and was found at higher concentrations in treatment plants serving higher numbers of IPPC
facilities. Note however that the larger treatment plants are those serving the higher number of licensed
facilities and are also located coastally. Saline intrusion may be causing the higher arsenic concentrations.
All other metals were ubiquitous across all non-domestic contribution bands.

Triazine Herbicides, Substituted Ureas and Acid Herbicides
Triazine herbicides were recorded above the LOD most commonly in the influent and effluent of waste
water treatment plants with <20% non-domestic contribution i.e. the more rural catchments. This is in
keeping with the findings of the correlation with PE Bands.
Substituted ureas were recorded in only a small number of samples. No correlation with non-domestic

Glyphosphate was generally recorded at higher concentrations in Round 1 which is attributable to seasonal
usage. No correlation with non-domestic contribution was discernible.
PAHs
Lower concentrations of PAHs were recorded in the influent of waste water treatment plants with <20%
non-domestic contribution. PAH concentrations were higher in the influent of treatment plants serving
higher numbers of IPPC industries. Removal efficiencies in activated sludge are high.
PCBs- Pesticides and Others
Tetrachloroethylene (PER) and Dichloromethane (DCM) were detected principally in treatment plants with
higher levels of non-domestic contribution, however given the low number of samples detected above the
LOD, it cannot be stated with certainty that there is a strong correlation.

SVOCs
Benzene, Toluene, Xylenes, Ethyl benzene and Di(2-ethylhexyl)phthalate were recorded above the LOD in
the influent of waste water treatment plants falling into all non-domestic contribution categories. The results
of effluent monitoring show however that SVOC concentrations and prevalence are higher in the effluents
of plants with <20% non-domestic contribution. This is more likely to be a function of the level and type of
treatment and whether the plant is operating efficiently rather than being related to catchment activities.

Toluene as BTEX
Water Supply
The potable water supply serving a catchment will impact the concentration of certain PRTR substances in
the influent to the waste water treatment plant. The constituents of the potable water will be source specific.
The concentrations at end of tap will be dependant on the level of water treatment provided prior to
distribution and also on the corrosivity of the water on the supply network (which is influenced by water
hardness and pH as well as by the plumbing materials themselves).
The European Communities (Drinking Water) Regulations (No. 2) 2007 require chemical and microbial
analysis of water supplies at the end of tap to assess compliance with acceptable standards. Many of the
chemical parameters monitored under the regulations are PRTR substances. The inventory of analysis
under the Drinking Water Regulations is therefore a good indicator of PRTR contamination in the water
supply and can be used to calculate the load to a treatment plant from water supply.
There are existing data gaps however which are inhibitory to the use of this data for the development of the
EPA Estimation Toolset. The overlap in population served by the waste water treatment plants and that
within the individual water supply zones is currently unknown and would require investigation at local level.
4.2.2 Collection System
The principal indirect source of PRTR substances to waste water treatment plant is from stormwater runoff
to the collection network.
Storm conditions can have the effect of diluting the waste water entering the treatment plant thereby
lowering the concentrations of certain substances in the influent. However peak flow conditions can also
289584/IWE/R/04/A 05 September 2012 20120905 - 289584 - Part A Final Report.doc

Effluent Characterisation Study
contain higher than normal concentration of other parameters. This is due to the effect of ‘washing’ these
substances from the surrounding catchment and flushing of sediments from the sewer system.
The effect of storm conditions on the concentration of PRTR substances in an influent to a treatment plant
is influenced by whether the catchment is serviced by combined or separate foul sewer, and the size of the
catchment. Runoff contaminant composition will be influenced by atmospheric inputs from activities within
the catchment (whereby catchments with greater industrial activity have greater inputs), intensity of road
usage and on the level of urbanisation.
PRTR substances likely to show up at higher concentrations due to urban runoff include zinc, cadmium,
lead and copper (mainly from vehicle emissions/tyre degradation), PAHs and PCBs (mainly from industrial
deposition) and pesticides/herbicides (used in the maintenance of road vegetation).
In many cases much of the stormwater will not pass through the treatment plants but will instead discharge
to the surrounding environment via the stormwater overflows within the collection system, pump stations
and treatment works. The monitoring of stormwater overflow discharge goes beyond the scope of this
study. Further study in this area is recommended for the purpose of updating the Estimation Toolset.
Of the eleven treatment plants included in this study six have stormwater holding facilities, namely
Mitchelstown, Dundalk, Waterford, Blarney, Ringsend and Watergrasshill. The treatment plant operators
were asked to report on whether stormwater was returned to the plant for treatment at the time of sample
collection. These plants were assessed to determine whether there was any likely relationship with PRTR
concentrations and storm events. (Please note that the influent sampling does not include returned
stormwater, and this assessment is indicative only.)
No correlation with metal and PCB concentrations was discernable. There was however a correlation
between the plants returning storm water and the concentrations of PAHs and pesticides in the influent.
While some correlation was identified this would need to be substantiated with storm water analysis.

4.2.3 Type and Level of Treatment
The type and level of treatment provided at a treatment plant can influence the removal efficiencies within
the plant. The treatment plants included in this study use activated sludge processes. The removal of
pollutants in conventional activated sludge systems is influenced by the retention time mixed liquor
suspended solids (MLSS) and airflow rates. These elements will influence the degree of volatilisation (and
air stripping), biodegradation and sorption of the PRTR pollutants from the wastewater that will occur during
treatment. For example, a higher degree of volatilisation is expected at treatment plants that apply diffused
air. Similarly higher removal rates through sorption are expected at plants using primary settlement and
those with longer retention times.
The eleven treatment plants were assessed with regard to the type and level of treatment provided. Each
plant receives preliminary screening for the removal of rags and large debris from the waste water stream.
The following additional treatment options are present in the eleven treatment plants and are shown in

General Parameters
There was no discernible relationship between Total Nitrogen concentrations in the effluent and the level or
type of treatment provided.
The average Total Phosphorus concentration in the effluent from plants without phosphorus removal was
higher at 2.26mg/l compared with 0.84mg/l for those plants with chemical Phosphorus removal.

Metals
Metal analysis for Round 3 provided a number of questionable results; most notably Molybdenum
was detected at very high concentrations in all effluent and influent samples. The decision was
taken to exclude all Round 3 metal results from the study for the purpose of developing the Tool.
Metals removal in municipal wastewater treatment plants results primarily from sorption or chemical-
physical processes. Metals are hydrophobic and have high sorption potential and will therefore sorb to
organic material in the wastewater. The removal of such material through primary settlement will also
therefore achieve metal removal. Coprecipitation of metals also occurs with chemical removal of
phosphorus. Ferric sulphate is used at the seven plants that apply phosphorus removal which facilitates the
precipitation of metals as sulphides. Thus plants providing phosphorus removal will also achieve high levels
of metals removal. Highest removal efficiencies are therefore expected at plants with both primary
treatment and chemical precipitation.

Lead and nickel were recorded above the LOD most commonly in the effluent of the Newcastle West, and
Mitchelstown treatment plants. It is believed that the short hydraulic retention time at these plants has
influenced the removal efficiency for these metals.

Selenium was reported in the effluent of treatment plants with primary and secondary treatment only. Note
however that Selenium was present in the influent to these plants only, it is therefore a characteristic of the
influent rather than a result of the treatment type.
Pesticides
No correlation was observed between the level and type of treatment and the concentration of pesticides in
the effluent.
Triazine Herbicides, Substituted Ureas and Acid Herbicides
Atrazine and simazine were detected in only a small number of influent and effluent samples. These
Triazine herbicides are hydrophilic and are not therefore readily removed through sedimentation. Removal
efficiencies through volatilisation are also low. Influent and effluent concentrations are therefore very
similar.
Substituted ureas were recorded above the LOD in only a very small number of samples. These
substances are difficult to remove by traditional activated sludge treatment due to their persistence, low
volatilisation potential and low biodegradability. Influent and effluent concentrations are therefore very
similar.

Effluent Characterisation Study
Acid herbicides have low removal efficiencies in activated sludge. They are hydrophilic and have low
volitization potential. Influent and effluent concentrations are therefore very similar.
PAHs
The principal mechanism of PAH removal is through sorption. It is therefore anticipated that plants using
chemical precipitation will have greater removal efficiencies. Influent concentrations were higher in the
larger plants. These are also the treatment plants that do not provide chemical precipitation. It is likely that
the high influent concentration is linked to the higher effluent concentrations in these plants. It is of note
also that the Ringsend treatment plant is overloaded and this will influence the effectiveness of plant
operation.

SVOCs
The principal mechanism by which benzene, toluene, xylenes and ethyl benzene are removed from the
wastewater is by volatilisation. All plants, with the exception of Mitchelstown, use activated sludgefor which
a high degree of volatilisation would be expected, particularly in plants with diffuse air systems. DEHP has
low solubility and high sorption potential. It also has low volatilisation potential. The principal mechanisms
of removal are therefore through sedimentation and chemical precipitation. DEHP was however found to be
common in the effluent across all treatment levels.

Effluent Characterisation Study
Good removal efficiencies were observed for Toluene. However removal efficiencies at the Mitchelstown
plant were consistently generally lower. Mitchelstown operates a trickling biofilter system with stone media
using natural draft airflow. Lower levels of volatilisation are achieved using this system. In addition, the
Mitchelstown plant is overloaded. This will negatively impact on removal efficiencies.

4.2.4 Inland or coastal Location
Catchments located in proximity to the coast are likely to be subject to saline intrusion into the sewerage
network which will impact upon the constituents in the wastewater.
Constituents of seawater which were measured in this study include chlorides and boron. Due to the
dissolved fractions present in the seawater, the conductivity and hardness differ significantly from inland
and coastal waters. Constituents such as arsenic and barium which are naturally occurring in seawater are
also likely to be present at higher concentrations in wastewaters from coastal catchments.

Effluent Characterisation Study
5.1 Overview of the Tool
The EPA Calculation Toolset (Version 4.0) has been updated to provide a more representative estimate of
the mass emissions of PRTR substances from waste water treatment plants based on monitoring of eleven
representative waste water treatment plants.
The monitoring results were analysed and compared to the characteristics of the catchment and treatment
plant to derive a correlation between the observed effluent constituents and concentrations.
The previous version of the tool relied on analysis from the Ringsend waste water treatment plant. Effluent
results from Ringsend were used together with flows from individual treatment plants to calculate an annual
mass emission.
The revised version of the Tool is representative of a broader range of waste water treatment plants. The
treatment plant characteristics assessed for the purpose of further developing the tool are:
� Population equivalent
� Percentage non-domestic contribution
� Type of treatment
� Coastal / inland location
The above descriptors, and constituents thereof, have been correlated with PRTR poppluant
concentrations in the effluent to provide better estimates of the mass emissions.
5.2 Assessment of Treatment Plant Characteristics & Trends
The results of the monitoring at the eleven waste water treatment plants suggest a correlation between the
catchment descriptors and the concentration of certain PRTR substances in the effluent.
5.2.1 Identification of the Principle Treatment Plant Characteristic Driving the
Trend in PRTR Effluent Concentrations
The association between the treatment plant characteristics and the occurrence and concentration of
PRTR substances in the effluent discharges from the eleven treatment plants was examined. When
assessing whether a trend existed in association with treatment plant characteristics regard was taken of
the range of concentrations observed under each characteristic descriptor and of the frequency of detection
above the LOD.
The occurrence and concentration of some PRTR substances was recognised to be strongly linked to
particular treatment plant characteristics e.g. certain metal concentrations were significantly higher in the
smaller treatment plants (<10,000PE). The recognised trends and the associated characteristics are
summarised in Table 5.1 and are presented in greater detail in Appendix B.

Emission concentrations were generated that are reflective of the observations made regarding the
concentrations of parameters associated with the treatment plant characteristics e.g. plants providing
phosphorus removal had much lower concentrations in the effluent. The average effluent concentration of
these plants was used as the emission factor to be applied where chemical phosphorus removal is
employed; conversely the average effluent concentration of the other plants was used to generate the
emission concentration for plants without phosphorus removal.
It is of note that a coincidence of particular characteristics occurs at the larger treatment plants included in
this study i.e. all treatment plants >50,000 PE (Dundalk, Waterford, Carrigrennan, and Ringsend) are
located coastally and do not provide phosphorus removal. All other plants included in the study provide
chemical phosphorus removal and are located inland.
The coincidence of this particular set of characteristics at the larger plants makes it difficult to determine
whether it is the size of the catchment being served, the level of treatment at the plant or the coastal
location of the plant which is the driving characteristic behind the higher/lower concentrations of certain
substances. For example, arsenic was recorded more frequently and at higher concentrations in the
influent and effluent samples of treatment plants >50,000 PE. The higher concentrations in the samples
may be a function of industrial activity in these larger urban catchments. However as the larger plants are
located coastally and are known to have high levels of saline intrusion, the higher concentrations may be a
function of location. Effluent concentrations were comparatively high compared to <50,000PE plants and
may be attributable to a combination of the lower metals precipitation that would be achieved where
chemical phosphorus removal is not employed and the already high influent concentrations.
5.3 Simple Substitution
In determing the values to be used in the Tool for the generation of the emission factors, regard was had to
the fact that many substances were not recorded above the limit of detection. The assumption that the
substance was not present and therefore not relevant in the Irish context could not be made in all cases
due in particular to complications caused by sample matrix interference and due to analytical limitations
which required the dilution of samples. As a result higher LODs had to be reported for many parameters
which meant that it could not be stated with confidence that the substance was not present in the sample.

Effluent Characterisation Study
Zero values could not therefore be automatically applied where a <LOD result was obtained as this might
not be reflective of reality.
In order to provide an accurate estimate of average effluent concentrations specific to the various
catchment characteristics a Simple Substitution approach was used for results reported as <LOD (i.e.
wherever a <LOD was encountered a single value was substituted). Other more complex methods for
addressing values reported as <LOD have been developed which are based on assumptions on the
distribution of data (distribution method) and extrapolation using above LOD results (robust method).
However the distribution method requires a high degree of knowledge on the typical distribution of
environmental data. Given that there is little research available on PRTR substances such an approach is
unrealistic. The robust method is difficult to apply whereby a large proportion of results are <LOD and
where there is a small sample number as is the case here. It is considered therefore that Simple
Substitution is most appropriate due to the small number of samples (maximum number is 44 per
parameter).
A number of simple substitution options were considered:
• Report the result as not detected i.e. as 0 (zero);
• Substitute the <LOD with the LOD value;
• Choose an arbitrary value e.g. 50% of the detection level;
• Choose a substitute value where 0 < value < LOD;
• Report the actual result found with a caveat regarding the confidence in its accuracy.
Issues arise with the direct substitution of the <LOD value with the LOD whereby the majority of results are
<LOD, the issue of raised LODs could potentially skew reporting of PRTR values in this way. The reporting
of a zero result would be non-representative. The application of an arbitary figure e.g. 50% of the detection
level across the board would also be non-representative for certain parameters. Case by case
assessments against each individual parameter were therefore conducted in order to determine the most
suitable simple substitution values to be applied. These assessments were based on published reports, as
cited in the references section of this document, on the use and presence in the environment of the
individual parameters as well as the likelihood of removal through activated sludge.
The proposed simple substitution methodology applied has the following general approach:
• Where a low percentage of the WWTP samples were reported as <LOD, the LOD was directly
substituted unless a specific catchment trend is reported/expected.
• Where a high percentage of samples were reported as <LOD (either 1 LOD or multiple LODs) a
substitute value was selected considering scientific papers on removal efficiencies in activated
sludge and on the likelihood for the presence of the parameter in wastewater / the environment.
Higher substituted values were used where there was greater water solubility, toxicity and
persistence of the parameter.

• Some substances (e.g. pesticides) are banned for use in Ireland. If not detected in any samples
above the level of detection than 0 was substituted, results from other studies were consulted to
verify, e.g. Teagasc, Marine Institute.

Effluent Characterisation Study
An auditable trail of the simple substitution values used for the generation of emission factors was
maintained by applying a colour code to <LOD values that required simple substitution. This colour code
was carried through all of our background datasets in order that simple substitution values may be instantly
differentiated from measured values. An example is presented in Table 5.3 where simple substation values
are highlighted in blue.

5.4 Emission Concentrations Used in the Tool
Effluent monitoring results from Rounds 1 to 4 associated with each parameter were extracted from the
database relative to the trends observed to be associated with the catchment characteristics and the
average value was calculated which was used as the emission concentration. The extraction of results
took the following approach:
No Trend Observed
Where no trend was observed for a parameter, the full range of effluent monitoring results associated with
that parameter from all waste water treatment plants was extracted and the average value calculated.
Population Equivalent Trend
Certain parameters were identified as occurring more frequently and/or at higher concentrations in
association with particular population equivalent bands. The PE bands allocated to the Tool are
‘<10,000PE’, ‘10,000PE – 50,000PE’, and ‘>50,000PE’. Effluent monitoring results for the parameters
associated with treatment plants falling into each PE band were extracted and the averge value calculated
to generate the emission concentration. The emission concentrations generated for parameters showing
variation across the PE bands are presented in Table 5.4. All concentrations are in mg/l.

Effluent Characterisation Study
Two parameters, Arsenic and Barium showed variation in concentrations across the PE bands but also
showed signs of influence by saline intrusion. Table 5.5 shows the emission concnetrations generated for
these parameters. All concentrations are in mg/l.
Table 5.5 Emission Concentrations for Parameters Linked to PE & Coastal Location

Arsenic and compounds (as As) 0.0006 0.0004 0.0022 0.0022
Barium 0.013 0.019 0.023 0.023
In this study, all plants >50,000PE were also located coastally. The influence of saline infiltration on plants
with a smaller population equivalent could not therefore be determined and the decision was taken to use
the 10,000 – 50,000PE values for plants >50,000PE that are located inland resulting in the following
scenarios:
� If a plant is >50,000PE and is coastally located the coastal values for arsenic and barium are
pulled used;
� If a plant is >50,000PE and is not coastally located the 10,000 – 50,000PE values for arsenic and
barium are used;
� If a plant is 10,000 – 50,000PE and is located inland the 10,000 – 50,000PE values for arsenic and
barium are used;
� If a plant is 10,000 – 50,000PE and is coastally located the coastal values for arsenic and barium
are used. These values may be slightly higher than what might be measured in reality as they are
associated with larger plants which might have industrial influences adding to the concentrations.
� If a plant is <10,000PE and is located inland the <10,000PE values for arsenic and barium are
used;
� If a plant is <10,000PE and is located coastally the <10,000PE values for arsenic and barium are
used i.e. coastal values are not applied on the assumption that limited saline intrusion wilol occur
given the small catchment size;
Level of Treatment Trend
Certain parameters were identified as occurring more frequently and/or at higher concentrations in
association with plants providing different types of treatment. The treatment options allocated to the Tool
fall into two categories: (a) Nutrient Removal, (b) Type of Treatment. The sub-categories under nutrient
removal are Phosphorus Removal Only - Biological/Chemical/Wetland, Nitrogen Removal Only,
Phosphorous and Nitrogen Removal, No Nutrient Removal. The sub-categories under type of treatment are
No Treatment, Primary Treatment Only, Secondary Treatment - Activated Sludge, Secondary Treatment -
Other, Tertiary Treatment - Filtration, and Disinfection. Effluent monitoring results for the parameters
associated with treatment plants falling into each treatment category were extracted and the averge value
calculated to generate the emission concentration. The emission concentrations generated for parameters
showing an association with treatment type are presented in Table 5.6. All concentrations are in mg/l.

Where the ‘No Treatment’ or ‘Primary treatment only’ option is selected, the Tool draws upon influent
sampling results rather than effluent sampling results with the logic that even where primary treatment is
provided the output will be more closely related to the influent samples than the effluent samples under this
study. The influent results utilised for the generation of emission concentrations for ‘No Treatment’ are
drawn from Round 1, 3 and 4 only. Influent monitoring results from Round 2 are not included as these are
representative of storm conditions. Note that the metal results from Round 3 were also excluded. Saline
intrusion did influence the concentration of certain parameters in coastally located plants. Specific coastal
concentrations were therefore generated for these parameters.
Inland / Coastal Location Trend
Certain parameters were identified as occurring more frequently and/or at higher concentrations depending
on the location of the treatment plants. Effluent monitoring results for the parameters associated with
treatment plants located coastally (i.e. where saline intrusionis likely to occur) were extracted and the
averge value calculated to generate the emission concentrations. The emission concentrations generated
for parameters showing an association with coastal locations are presented in Table 5.7. All concentrations
are in mg/l with the exception of conductivity.

Boron 0.29 0.06
Fugitive Emissions
Influent monitoring results from Round 2 were used to generate emission concentrations to be applied to
fugitive emissions. Round 2 sampling was conducted in storm conditions. It is considered that the Round 2
influent monitoring is closely representative of typical fugitive emissions from storm overflows, following first
flush. Note that the Ringsend Round 2 results were excluded as the sampling at Ringsent for Round 2 was
postposed until after the storm event.
The Round 2 influent results were assessed for any links between PE bands and concentrations of PRTR
substances. No correlation was determined. Emission concentrations were therefore generated using the
full range of influent monitoring results for Round 2 for all treatment plants. Saline intrusion did however
influence the concentration of certain parameters in coastally located plants. Specific ‘coastal fugitive
emission concentrations’ were therefore generated for these parameters.
The simple substitution values used in the generation of fugitive emission were the same as those applied
to the treated emission database.

5.5 UWWTP Emissions Estimation Toolset Input Requirements & Functionality
The updated AER / PRTR UWWTP Emissions Estimation Toolset is an excel-based electronic tool which is
comprised of the following user interfaces:
1. “Introductory Guidance”: This section of the Tool provides an overview of the input and output
elements of the Tool and highlights the input functions of the Tool as well as providing definitions to
assist the user in the selection of the catchment characteristic features most appropriate to their
treatment plant.
2. “Sources”: This section of the Tool provides an overview of the information sources used in the
gerneration of emission concentrations.
3. “Water Emissions Data Input”: This is the only user data input interface of the Tool. Data entry is in two
forms. The first is the direct input of facility details including location and annual effluent flow. The
second input simply comprises a series of drop down menus from which the user selects the
catchment characteristics most appropriate to their treatment plant. The input fields are colour coded
to identify to the user the type of data entry required. The Water Emissions Data Input section of the
Tool is shown in Figure 5.1.

93
Effluent Characterisation Study
4. “Water Emissions Background Data”: This is the emission concentration element of the Tool.
Depending on the catchment characteristics inputted by the user, the Tool will draw on different sets of
emission concentrations held in this section of the Tool. The database includes emission
concentrations representative of all permutations of the catchment characteristics that may be inputted
to the tool. Emission concentrations for fugitive emissions are also included under this section of the
Tool. This datasheet is hidden from view in the tool.
5. “Measured Vlaues”: This section of the Tool allows measured values to be used where available
instead of estimated concentrations. The Measured values section of the Tool is shown in Figure 5.3.
Figure 5.2 Extract from Updated Estimation Tool – Measured Values Interface

6. “Water Emissions Estimates”: This section of the Tool pulls the emission concentrations, appropriate
to the inputted catchment characteristics, from the Water Emissions Background Data sheet and
estimates the annual mass emissions of treated effluent discharges and fugitive emissions from the
treatment plant using the discharge volumes provided. The Water Emissions Estimates section of the
Tool is shown in Figure 5.3.
Figure 5.3 Extract from Updated Estimation Tool – Water Emissions Estimates Interface
7. “Releases to Water Output Table”: Is the summary of all estimated mass annual emissions from the
waste water treatment plant. This element of the Tool requires some limited user input. The user is
required to provide mass annual emission data for accidental discharges from the plant. A total mass
annual emission value is then generated for each parameter and is comprised of treated emissions,
fugitive emissions and accidental emissions. Where the EU reporting thresholds are exceeded this is
highlighted for information purposes. The Water Output Table is shown in Figure 5.4.

5.6 Validation
The emission concentrations generated for use in the Tool were validated against the following data:
� Mitchelstown WWTP (PRTR submission 2011 - measured data)
� Watergrasshill WWTP (PRTR submission 2011 - measured data)
� Newcastle West WWTP (2011 AER – Priority Substances Screening data)
� Athlone WWTP (2010 AER - Priority Substances Screening data)

289584/IWE/R/04/A 05 September 2012 20120905 - 289584 - Part A Final Report.doc
96
Effluent Characterisation Study
Validation was carried out by comparing measured effluent data from the above mentioned sources against
the emission concentrations generated in the new Toolset. The emission concentrations were validated
against the data that was representative of the characteristics of the individual treatment plants i.e. where
monitoring data for Mitchelstown was used, the emission concentrations were validated against the data for
a <10,000 p.e. trickling filter plant which is located inland and has phosphorus removal. Similarly, where
monitoring data for Waterford was used, the emission concentrations were validated against the data that
was representative of a >50,000 p.e. activated sludge plant coastally located and does not employ
phosphorus removal.
The emission concentrations generated for untreated discharges were validated against the Buncrana
WWDL screening data. Measured values were not available for the majority of substances and many
substances were reported as <LOD. The LODs achieved for the Buncrana monitoring were considerably
higher than those achieved in this study. Where measured values were reported above the limit of
detection, there was strong agreement between the measured values and the emission concentrations.
It must be noted that for many of the PRTR substances monitoring data was unavailable and as such no
validation could be performed. In addition no monitoring data was available for the purpose of validation for
the Portarlington and Ballinasloe treatment plants. These plants do not currently hold a discharge licence
under the Waste Water Authorisation Regulations.
All validation data is presented in Appendix C. The emission concentrations were in broad agreement with
measured values for the majority of substances.

Effluent Characterisation Study
It is recommended that additional investigations and studies would benefit the further development of the
toolset.
The plants included in this study were chosen to be reflective of a variety of PE bands catchment types. A
coincidence of particular characteristics occurs at the larger treatment plants included in this study i.e. all
treatment plants >50,000 PE (Dundalk, Waterford, Carrigrennan, and Ringsend) are located coastally and
do not provide phosphorus removal. All other plants included in the study provide chemical phosphorus
removal and are located inland. It would be beneficial to the further broadening of the tool to investigate the
relationship between PRTR substances and plants with high PE but which are located inland.
The plants included in this study were mainly of an activated sludge type. In order to generate a wider
range of emission factors for varying treatment options it is recommended that further study should be
conducted in this area focusing on a broader range of treatment options and levels of treatment to include
no treatment up to and including tertiary treatment.
It is also recommended that the focus of plant selection for future studies should be towards plants with a
broad range of non-domestic contribution within a number of PE bands. This may allow the inclusion of an
additional catchment descriptor in the tool which will further differentiate individual plants from one another
and ultimately their PRTR contributions to the environment.
A significant gap in the monitoring data pertains to fugitive emissions. Monitoring during storm conditions
will provide a better estimate of fugitive releases to the environment. It is recommended that storm water
should be sampled using composite sampling on a flow proportional basis using individual 1 litre
containers. This approach will give an indication of the trend in concentrations of PRTR substances in the
storm water over the duration of the storm and may allow an association between storm intensity and
PRTR concentrations to be derived. An investigation into the relationship between stormwater constituents
and the percentage of combined sewer in the catchment as well as the level of urbanisation of the
catchment would also benefit the the tool.
